JOHN HENDERSON GOURLIE, 0F WINNIPEG, MANITOBA, CANADA.

To all whom it may concern:

Be it known that I, J OHN HENDERSON GOURLIE, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Beaters, of which the following is the specification.

The invention relates to an improvement in boaters especially adapted for beating or whipping cream, eggs or other such like produce and the object of the invention is to provide an inexpensive and durable beater which will effectively and quickly beat the material in which it is inserted when manipulated in a proper way by the attendant.

A further object of the invention is to provide a beater which can be readily taken apart for cleaning purposes.

With the above objects in view the invention consists essentially in a cylindrical body piece having one end open and the other end closed by a cap, a hollow plunger rod, a handle or knob on the rod, a pair of perforated disks carried by the rod and a valve at the lower end of the rod below the disks, the parts being arranged and constructed as hereinafter more particularly described and later pointed out in the appended claim.

Figure 1 represents a side view of the complete device. Fig. 2 is a longitudinal sectional view centrally through the same. Fig. 3 an inverted plan View of the beater.

In the drawing like characters of reference indicate corresponding parts in each figure.

1 represents a cylindrical body piece having the ends thereof open and supplied toward the lower end with a series of circumferentially disposed perforations 2. The upper end of the body piece is normally closed by a cap 3 fitted over the same.

l is a hollow plunger rod located in the cylinder and passing upwardly slidbly through the cap piece 3. The plunger rod is fitted at the upper end with a handle or knob 4c and carriers at the lower end a pair of permanent oppositely dished and perforated disks 5 and 6, the disks being designed to slide in the cylinder more or less in the form of plungers.

7 is a valve located at the lower end of the plunger rod and designed when the device is in use to close at times the lower open end of said plunger rod.

8 is a cage carried by the disks and retaining the valve in position.

When the device is to be used, say for whipping cream, the lower end of the cylinder is immersed in the cream and the plunger rod is reciprocated, the one attending holding the cylinder, with one hand, stationary in the cream and reciprocating the plunger rod with the other hand. On the downstroke of the plunger rod the valve 7 seats on the lower end of the plunger rod, this being effected by the pressure of the liquid on the valve. The liquid is passed in streams on the down-stroke through the perforations in the disks 5 and 6 to the upper side of said disks. On the lip-stroke the valve 7 unseats by the action of gravity and permits air to enter the liquid during the upstroke through the hollow center of the plunger rod and permits the liquid previously displaced to the upper side of the disks to escape back again in streams through the perforations in the disks to the under side thereof. The cream is accordingly effectively agitated and mixed with air so that it is quickly whipped.

As the cap can be readily removed the device can be easily kept clean which is an important feature from a sanitary standpoint as it allows all the parts to be readily washed.

What I claim as my invention is The combination comprising a hollow cylindrical body piece having the lower end open and the upper end provided with a suitable cap piece, the lower end of said cylinder being provided with a plurality of circumferentially directed perforations, a hollow plunger rod inserted within the cylinder and extending slidably through the cap piece, a handle located on the upper end of the plunger rod, a pair of adjoining oppositely dished perforated disks permanently secured to the lower end of the plunger rod and slidable within the cylinder, a valve cage carried by the lowermost disk and a valve within the cage designed to seat on the lower end of the plunger rod, as and for the purpose specified.

Signed at Winnipeg this 8th day of July 1913.

JOHN HENDERSON GOURLIE.
